1 Dehumidifier capacity is generally measured by how many pints of water a unit removes from the air in 24 hours. 2  A mini-dehumidifier (1-10 pints) for a bathroom, closet or under a counter usually costs $40-$70.
A dehumidifier that removes 30 pints of moisture daily is generally good for areas up to 400 square feet. Dehumidifiers that remove 50 pints of moisture daily are generally good for areas up to 800 square feet and 70 pint dehumidifiers are generally good for areas up to about 1500 square feet.ost portable home dehumidifiers come with a water tank or bucket; a few do not-they just offer continuous drainage via a hose. Water buckets range in size from about 5 pint capacity to about 20 pint capacity.
